	Combining chemical evidence from meteorites with the latest computer simulations, scientists show how, nearly five billion years ago, a supernova shock wave could have swept through a cloud of dust and gas and caused it to collapse, eventually forming our sun and the planets—if it didn't blow the baby solar system apart first.</p>

<p>NOVA investigates the story of cannabis from the criminalization that has disproportionately harmed communities of color to the latest medical understanding of the plant. What risks does cannabis pose to the developing brain? How much do we know about its potential medical benefits? As cannabis becomes socially accepted, scientists are exploring its long-term health consequences. (Premiered September 29, 2021)</p><p>Check out a previously recorded panel discussion and audience Q&amp;A featuring experts and producers from "The Cannabis Question" <a href="https://youtu.be/nSTT5RZ_hxA">here</a>.</p>

<p>As state-legalized cannabis spreads, NOVA explores its little-known risks and benefits.</p>
